Adafruit's [http://www.adafruit.com/products/555 16x24 Red LED Matrix Panel] uses the [http://www.adafruit.com/datasheets/ht1632cv120.pdf HT1632C LED driver]. The driver has the ability to dim and flash and they can be chained together to produce large displays. The code developed for this MiniProject is based on Adafruit's [https://github.com/adafruit/HT1632 original HT1632 github repository]. It also uses a modified version of BoneHeader.h to support C++ originally from [https://github.com/millerap/ECE497 Andrew Miller's github repository].

Inputs and Outputs

A single matrix panel can be powered directly off of the BeagleBone's 3.3V supply (running only on USB power). The interface is a bit-banged serial interface requiring 3 pins: chip select (active low), write clock (rising edge trigger), and data.
